================================================================================================
This is Rakudo running in the debugger, which often allows the user to generate useful back-
traces to debug or report issues in Rakudo, the MoarVM backend or the currently running code.
This Rakudo version is 2021.06.87.geceeb.5083 built on MoarVM version 2021.06.281.g.1.db.0.f.3.bb.9,
running on linuxmint (20.Ulyana) / linux
Type `bt full` to generate a backtrace if applicable, type `q` to quit or `help` for help.

This is Rakudo running in valgrind, a tool for debugging and profiling programs.
Running a program in valgrind usually takes *a lot* more time than running it directly,
so please be patient.
